Quantitating ruminal turnover.

W C Ellis, J H Matis, C Lascano

    Federation Proceedings

    Summary
    This summary is machine-generated.

    Understanding in vivo kinetics in ruminants is crucial for analyzing digestion. Measuring ruminal turnover of feed residues requires isotopic labeling or rare earth elements, considering ingestaflow as a complex, multicompartment process.

  • Consideration of mathematical methods for multicompartment ingestaflow.

    • Main Results:

    • Isotopically uniform feed particles are effective for measuring turnover.
    • Rare earth elements offer an alternative for tracking feed residues throughout the digestive tract.
    • Mathematical modeling must account for ingestaflow as a multicompartment system.
